Be it known that I, CARL.' G. L UNDIN, a subjeet'of the King of Slweden and N orway," residin the county of Kings and and useful Improvements in Automatic Feeders, of which the following is a specification. This invention relates to improvements in an apparatus' to be usedy for automatically supplying materialv of various kinds in suits. able quantities, and while I have shown itas Y being used, in connection with 'an Yaeetylene-v gas generator for lfeedingcarbid-thereto, yet

-it maybe used for V"provide a feeder of the ter which may be automatic in its operation- ,is shut o'ii until it is applicable for sponts .or chutes or Weighing-machines, or

and it consists in certain peculiarities of the construction, novelarrangement, and operation 'of the parts thereof,` as will be herein.- after moref' fully set forth and Vspecifically claimed.. 1

vThe principal bject'of the invention 1s to above-named'y characandshall besimple an( inexpensive mfits con-e l struct-ion', strong, when a sufficient quant-ity' of' the material,-

durable, and* so made that shall have, passed into 'the dumping-bucket as to discharge which operation the supply another chargeis desired.

`Other` objects and advantages of the inventhe material', 'in

- tion will 'be disclosed in thesubjoined descrip.'

tion and explanation.`

In order to enable others skilled in the art to which nay-invention pertains tomake and use the. same, I will now proceedto describe it, referring to vthe accompanying drawings,

"in which* Figure 1 'is avertial sectional view,partly 1n elevation, of au acetylene-'gas generator in connection therewith. Fig. 2 is a detached view, in side elevation, of the '-feeder, showing the parts arranged in positlon' forsupplying material to the'dumpmg or discharging bucketor vessel.

spending parts throughout the'dierent views ofthe drawings'. V- 5. Thereferencefnumeral104 represents the tank ofi an acetylene-generator, which may `be,- made .of ny suitable form or material, but preferably cylindrical.

Within this vessel vis m'ovably' fitted a'gasometerlL-which is vertically' guidedjby means of a support 12,

secu red 'to the vupper portion of the' cylinder 10. orsaid tank.z The lower vportionzotthe tank -is' provided witha'n inclined ii'or 13,

which, together withfthev horizontal parti tion .'14, forms a compartmentforithe reception of a quantity of vwaterfj 15,fin Whichtlie carbid is dischargedQthroughfjaf ehu Y A eating with' 'said' 'compa rtrne upwardly' on the ,outside o nd extending he tank. 'Ihc owerV portion of thefcompartrnent formed by the loor13- jand partition '14 is provided with a'faue'et 1 7, by means of which the water may =be withdrawn fromsaid compartment. 'The central portion of the partition 14: is- .provided 'with an 'inv erted funnel 1-8,

the -upper end of which is provided with a series of openings19 to permit ot' the escape of gas' generated bythe action'of the wa ter on thecarbid in thejloiver' compartment.' The upper end of the funnel 1,8` isclosed by means of a cap 20, which is usnallyevlim' drieal 1n shape, and 1s provided in its lower portion with a series of openingsQl to' permit ot' tle'discharge, of lthegas. l'Vithin that part of .the tank 10 above the partition 14 is a q uantity of water 15, which submerges the lower portion efthe cap 20, so passes through the openings 21 it will also washed thereby. water it will fill the space'betwecn the top ot' the gasometer 11 and the upper surface of the water and. by its expansive force will cause the gasometer to use on its support. Locatedon the outer surface of the tank 'l0 above the ike numerals of reference refer 11i eorre- I 6, comr'nurii- 1 that when the gas the water and he As the gas rises from the IOO ' vessel having its upper and front portions upperl end of the chute 16 is a carbid-receptacle 22, the lower end of which communicates with and supports the supply chiite or conduit 'Q3 of the feeder, which may be provided at its upper end with a hopper 24 to receive the material. '.lhis chute or conduit is provided on each of its sides with a depending supporting-ariii 25 for the lower portion of the discharging oi' dumping bucket, which is pivotall v secured thei'ebetweeii. Pivotally secured to the lower portion of the sides of the chute 23 is a cheek or check-valve, which comprises a' bottom or main portion 26, having at each ot' its side edges a forwardly-extending side QT, between which the supply-chiite 23 is located. The i'ront or discharging end of the check is bent to form a downward extension 28, which overlaps the rear portion of the d ii mpi ng or discharge bucket, as will be clearly seen by reference to F-ig. 3 of the drawings. Secured transversely on the bottom 26 oiftlie check-valve is a rod 29, the ends of which project slightly beyond the sides 27 and engage slotted arms A30, one of which is secured to .25

each side 'of the dumping vo rf, discharging bucket. These arms are slightlylcurved, as

shown, so as to permit of the eas'yoperation of the rod or shaft 29 inthe movements of the check valve and duinping.- bucket. 'lliis bucket bis a substantially rectangular-shaped open and is pi votally secured at its rear lower corner'on a rod or shaft 32, extending across and uniting the lowerends of the supports 25,

the upper ends of which are secured to the Asupply chute or conduit 23, as is clearly shown A in Fig. 4 ot' the drawings.

wardly and upwardly Vfrom the upper portion' Extending outof each of the sides of the bucket 31 is an arm "33,' to which is pivotally secu red a door 34, 1 used for closing and opening tliefront-portion. of said bucket. Pivotally secured to the Jr'ront lower-'portion of the bucket 31 is a. bail 35, to the upper middle portion of which is loosely connected 4at one 'of its ends a rod 36, the other end 'of which may pass throughtlic iiooror a '-I'ilatforniinot shown) or may be otherwise suitably supported, vso that it can be raised hand, it' desired. i

lnFig. 1 of the drawings I have shown the rod 36 as `passing through the lloor of a box-like casing 38, mounted on the upper end of the chute 16, and also as passing through a projection 39 ori the kcarbid-receptacle 22.

In thisliigurethe rod; 36 is shown as having at'itsfupperenda lateral projection 40 to en gage a lng 41 on a bar 42, which is i'iivotally connected at its upper end to one end of a lever 43, which is fulcriimcd on the upper portion-ot' the support '12 and connected at its other end by means of a rod 44 to the. top of the gasonietcr. The lower end of the bar 42 is provided with an enlargement 45, which increases in size toward its bottom. Extending horizontally across thc casing is, a rod 46, t with which the enlargement 45 on the bai- 4Q eration of'gas,'whicl i passes through the fun ncl 18 into the gasometer 11, so as to raise the same to the position shown by continuous lines in said iigure, in which operation thc enlargcdend 45 of the ba'r 42 will bclowered, so

as to bring the lug '.41 in' position to engage the projection 4Q on the rod 36, thereby raising the bucket 31 and the check-valve., so that the latter? willshut off the supply of carbid.

When the gasometer is further raised, itis evident that the bar 42 will be thrown out-of engagement with the projection 40, thus allowing the bucket 31 to turn on its pivotand again discharge its contents. f 1n using my'feeder for discharging coal, or other material substantially the saine operation as above set forthis performed, and

it is apparent that' the dumping-bucket may be operated through the medium of the'rod 36 and bail 35 and by hand, ifdesired.v

Having thus fully described vmy invention,

Letters Patent, is-v The combinati n with a. supply chute or conduit, of a` check-valve embracing and extending under the lower 'portionf the, chute 'and pivotally supported, a dumping-bucket pivotally'siipported below said valve adcomwhat I claim a's-new, and desire tosecure by 'municating therewith, a slotted arm on each side' of the-bucket in loose engagement with the 5 valve, 'andmeansconnected to the front/ of the i bucket torase and lower the saine, substaii tially as described."
